Arclight
Sendgame support
supportsp_generatordpselectric
Arclight stands out as a top pick because her low-cooldown Combo Skill feeds a steady stream of SP back into the team. That strength comes with a caveat: the Combo Skill only fires on Electrification, so she needs a partner capable of applying Electric Infliction, since her own kit only provides it through her Ultimate. Her Electric DMG buff from the Battle Skill is gated behind every third Electrification use, which drains SP, so it is better treated as a bonus rather than her main function.
This is Arclight's endgame support configuration, built to maximize both her SP generation and the strength of her Wildland Trekker buff. Thermite Cutter carries an ally-wide attack boost while the Frontiers set turns every SP recovery into a temporary team damage increase, and the Redeemer Seal off-piece pushes Intellect and Ultimate Gain so her Electric DMG buff scales higher and her Ultimate comes back faster. Because her damage happens mostly off-field, the goal is to keep the Electrification loop running so the Combo Skill keeps feeding SP to the rest of the team. Use this setup in Electric-centric compositions where at least one other operator can apply Electric Infliction.
Insights
Core Mechanics
- Peal of Thunder is a low-cooldown Combo Skill that damages enemies and refunds SP, but only triggers when an enemy is Electrified or when that Electrification is consumed.
- Tempestuous Arc blinks to the target for two slashes, and consumes active Electrification for an extra Electric hit plus SP recovery.
- Exploding Blitz is her only self-contained source of Electric Infliction, and it converts existing Infliction into forced Electrification after a short delay.
- Because she has no innate Electric Infliction outside the Ultimate, she must be paired with another Electric applier to keep her Combo Skill firing.
Scaling
- Intellect directly scales the Wildland Trekker teamwide Electric DMG buff, so stacking it improves her support output as she is invested into.
- Ultimate Gain is the other key growth stat, giving her more frequent Exploding Blitz casts for additional Infliction or Electrification windows.
- Early on she functions mostly as an SP battery; the Wildland Trekker buff only becomes meaningful once Intellect totals climb.
Team Role
Arclight slots into Electric-focused compositions as an SP engine and secondary damage dealer rather than a pure buffer. Her Combo Skill has a very short cooldown and feeds SP to the whole squad whenever Electrification is present, so she pairs best with at least one other operator who can inflict Electric. The rotation revolves around stacking Combo Skill casts: fire Peal of Thunder first, then use Tempestuous Arc to retrigger it, and time Exploding Blitz on an already-Inflicted target so the delay covers both the Infliction and the resulting Electrification. Teammates like Zhuang Fangyi can exploit either the raw Infliction or the Electrification depending on what their own kit wants. Her damage is largely off-field, so she is usually played as a support anchor while another character holds the field.

Explanation
Thermite Cutter is chosen first because it spreads an attack buff to the whole party while being easy to acquire from the weapon selector tied to the New Horizons banner.
OBJ Edge of Lightness works as a fallback that boosts Heat and Electric damage, but its benefit is narrower than the teamwide buff Thermite Cutter provides.
Fortmaker is a pure stat stick option — it doesn't grant team buffs, but its Intellect and Ultimate Gain feed directly into her Wildland Trekker scaling and Ultimate uptime.
Frontiers with a Redeemer Seal off-piece is the gear core: the set rewards SP recovery with a party damage buff, and the off-piece stacks the exact stats her talent wants.
Notes
- Thermite Cutter gives a teamwide attack buff on top of the Frontiers set, letting Arclight amplify allies while still restoring SP.
- Redeemer Seal is used as the off-piece for its Intellect and Ultimate Gain, feeding both the Wildland Trekker buff and her Ultimate cadence.
- The Frontiers set reduces the wearer's Combo Skill cooldown, which lines up perfectly with her SP-generating rotation.
